Title (EN) DOWN THE HOLE DRILLING MACHINE AND METHOD FOR DRILLING ROCK
(FR) MACHINE DE FORAGE DE FOND DE TROU ET PROCÉDÉ DE FORAGE DE ROCHE
Abstract:
(EN) A down the hole rock drilling machine and a method of drilling rock. The drilling machine comprises a casing (15) inside which is a control sleeve (20). A reciprocating piston (19) is arranged to move inside the control sleeve and control feeding and discharging of working chambers (20, 21). Between the control sleeve and an inner surface of the casing are all the fluid passages (28, 29, 30, 31) needed for fluid routing. The piston opens and closes transverse openings and controls the work cycle.
(FR) L'invention concerne une machine de forage de roche de fond de trou et un procédé de forage de roche. La machine de forage selon l'invention comprend un tubage (15) à l'intérieur duquel est disposé un manchon de commande (20). Un piston alternatif (19) est disposé de sorte à se déplacer à l'intérieur du manchon de commande et à commander l'alimentation et l'évacuation de chambres de travail (20, 21). Entre le manchon de commande et une surface interne du tubage sont formés tous les passages de fluide (28,29, 30, 31) nécessaires à l'acheminement de fluide. Le piston ouvre et ferme des ouvertures transversales et commande le cycle de travail.
